Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

A lightweight MCP (Model Context Protocol) server that enables AI coding assistants to interact with Google's Gemini AI through the official CLI. Works with Claude Code, Cursor, VS Code, and other MCP-compatible clients. Designed for simplicity, reliability, and seamless integration.

✨ Features

  • Direct Gemini CLI Integration: Zero API costs using official Gemini CLI
  • Three MCP Tools: Basic queries, file analysis, and web search capabilities
  • Stateless Operation: No sessions, caching, or complex state management
  • Production Ready: Robust error handling with configurable 60-second timeouts
  • Minimal Dependencies: Only requires mcp>=2,<3 and Gemini CLI
  • Easy Deployment: Support for both uvx and traditional pip installation
  • Universal MCP Compatibility: Works with any MCP-compatible AI coding assistant
  • Modern Python: Uses pathlib and modern type hints (Python 3.10+)

Questions

What is the Gemini Bridge MCP server?

A lightweight MCP server bridging AI agents to Google's Gemini AI via official CLI

What tools does Gemini Bridge expose?

3 in total: 1 read-only, 2 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Gemini Bridge safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Gemini Bridge need?

No credential environment variables were found in its source, so it appears to need none.

How current is this page?

The grade is for one exact copy of the source (5c2511dc88b9), read on 2026-10-07. The repository is watched and re-audited when it changes.
